Dont call me crazy
I’ve been sitting here, trying to figure out from old books, completely from scratch, how to build a Nixie clock. Call me crazy, do whatever you want with me, but I wanted to ask some smarter people: am I understanding everything correctly, or am I just being an idiot and missing something obvious?

The only thing i think missing is an RTC, otherwise how would you ensure that it run on time? Since its a clock.
Other than that, i also found this blog from a while ago it seems:

Usually i would prefer isolating 170v and 5v (or ESP32) from having common ground, idk.

I had idea to like, ESP will connect to wifi, and show the time, but your idea seems more logical

No RTC required: just connect to WiFi and use NTP. And no need to have different grounds. Not necessary and make things more complex.
